This article was extremely helpful in providing advice on one of the most annoying and persistent problems in photography, removing unwanted spots, objects, and/or people from pictures. It was really interesting to see all of the different ways or tools to use. The spot healing brush, clone stamping tool, or going into the content aware workspace tab are all different options for removing unwanted objects. I love how many tutorials are available for Photoshop and want to spend more time finding more of them!
